There’s something magnetic about a woman whose life begins to make sense in reverse.
Not because it was neat, but because every thread, the science, the grief, the motherhood, the pivots, the lived experience, starts to reveal itself as part of one larger pattern.
That’s what I felt reading Mireille Vega’s answers. Known to many as Dr. Mimi V, she’s 53, a biochemist and founder of VGAM Biome, where her work is rooted in oncology, immunology, microbiome research, and the belief that skin is not just surface, but a living ecosystem shaped by hormones, stress, chemistry, and lived experience.
What I loved most is the sense of convergence. This is not reinvention for the sake of reinvention. This is recognition. The moment where everything you’ve lived begins to become useful.
Who are you, and what season of life are you in?
I’m Mireille Vega, Accredited Chemist, PhD, though most people know me as Dr. Mimi V. I’m a biochemist, former biotech executive, and founder and CEO of VGAM Biome, where I lead what I call the Skin Science 3.0 movement. My 30 year career was shaped by oncology, immunology, and microbiome research, and all of it eventually converged into a single idea: that skin is a living ecosystem influenced by hormones, stress, and lived experience, and that caring for it should be simple, adaptive, and grounded in real science.
I’m 53, born in Montreal, raised between a French Canadian artist mother and a Spanish immigrant father. I’ve lived in three countries, built a business from scratch, lost both my parents, and navigated my son’s brain tumour. Still standing, still curious.
This is my season of convergence. The book I’m writing, the brand, the mission to help people care for their “one human skin” with intelligence and intention, and to see health as something that goes far deeper than the surface. It’s all clicking into place. Took a while. But that’s kind of the point.
What surprised you most about your 50s?
How much I stopped apologizing for being exactly who I am.
I always knew who I was. I just spent a lot of energy managing how that landed for other people, which turns out to be exhausting and also completely unnecessary. The people who need what I offer find me. That realization was a genuine surprise, a huge relief and major empowerment.
One thing you’ve stopped doing (and you’re better for it):
Forcing outcomes. I used to say yes to everything and then make it work through sheer multitasking. If it didn’t work one way, I’d try another, all at once. Now I let things go. I focus on fewer things, give space for solutions to arrive, and trust the process. The moment I stopped pressing, the answers started coming to me.
One thing I’m choosing instead:
Alignment. Before I say yes to anything, whether it’s an opportunity, a collaboration, or a commitment, I ask whether it actually serves the mission. I’ve become almost allergic to things that fragment my energy. When something is truly aligned, you feel it in your whole system, and that has become my filter for everything. And you know how I know? I listen in. I listen to my body, to my gut. It knows alignment.
One boundary I now honour, no apology:
My solitude. Meditation is non-negotiable for me, and creating space for stillness is strategic rather than selfish. As a founder, your internal state is your company’s operating system. When I’m scattered, everything is harder. When I’m centred, clarity arrives fast. Protecting that space is the most important work I do.
Also, I no longer hesitate when my gut says no. I’ve learned, the hard way and more than once, that when something feels like anxiety rather than excitement, that’s information. The moments I suffered most were those when I ignored that signal. A difficult boss I stayed under too long. A partnership I should never have entered. My hesitation was the sign, and I don’t override it anymore.
One micro-decision that changed everything:
Asking to be moved from oncology to immunology after my son was diagnosed with a brain tumour.
It looked like a step sideways, and honestly it felt like survival at the time. But it was in that immunology work that I discovered the skin-gut microbiome connection, the missing element I’d been searching for since my twenties, the scientific insight that became the entire foundation of VGAM. What felt like escaping was actually moving toward everything I was meant to build. I just didn’t know it yet.
One practice that keeps you steady:
Run or walk in nature. My brain processes everything simultaneously, which can be a lot, but movement outdoors creates a rhythm that quiets the noise. Some of my clearest thinking has happened on a trail or by the water, in the moments when I’m not producing, not performing, not explaining. Highly recommend.
One belief about midlife you no longer subscribe to:
That slowing down is wisdom.
I think we’ve been sold this idea that midlife means pulling back, becoming less. I see the opposite. You finally have the knowledge, the clarity, the courage, and enough scar tissue to do the real work. I’m more focused and more purposeful at 53 than at any other point in my life. And I’m at peace with that, because I know what I’m building and why.
The best thing about being in your 50s:
You’ve earned your filter. Decades of being misled by industries, by systems, by people, and you finally know the difference between what’s real and what’s noise. I’ve always had a strong radar for things that don’t add up. But in my 50s, I no longer try to fix it. I simply move on. That saves an enormous amount of time and energy. It’s one of the great gifts of this decade.
Complete this: At 50+, I am…
At peace. I’m saying the full sentence. Or choosing to not say a thing when it’s just noise. I enter the room I choose rather than try to fit the room. I know what I stand for. I know who I’m here to serve. And I know that your skin reflects your chemistry, and your chemistry reflects your life.
At 50+, I am…
the most honest version of myself, and that, as it turns out, is also the most effective one.
This week, I want women turning 50 to remember:
Everything you’ve lived is a foundation, not a liability.
Every hard thing you survived, every connection you made, every truth you finally told yourself. The decade ahead is about recognition rather than reinvention. You already have everything you need. It’s all connected. Trust the chemistry of your own life.
My Note to My Future Self
What I love about Mireille’s answers is the way she speaks about life as something connected.
Not random. Not wasted. Not a collection of wrong turns and detours. Connected.
That idea really stayed with me, because I think so many women reach midlife and start questioning whether they are too late, too scattered, too complicated, too full of different chapters to make sense. But sometimes the meaning only appears later. Sometimes what felt like survival becomes preparation. Sometimes the sideways move becomes the doorway. Sometimes the thing you thought took too long was actually becoming ready in its own time.
And I love what she says about no longer forcing outcomes. That feels like such a mature kind of power. Not passive. Not detached. But grounded enough to stop pressing on doors that are not opening and wise enough to listen when the body says no.
Maybe that is one of the gifts of this decade. You stop trying to fit the room. You enter the room you choose.
If you’re following along this week
My Stop: Where am I still forcing outcomes instead of allowing clarity to arrive?
My Start: What would choosing alignment look like before saying yes?
My Boundary: Where do I need to protect my solitude, stillness, or inner clarity?
My Micro-decision: What past “sideways move” might actually have been part of the path?
My Practice: What kind of movement or nature time helps quiet the noise in my mind?
Journal prompt: What if everything I’ve lived is not a liability, but the foundation for what I’m here to build next?
85 Weeks to Fifty is a series born from one woman walking herself towards fifty in the company of other women’s wisdom. If their stories are landing, if you’re finding yourself in their honesty, there is a space where this conversation continues, week by week, not just in interviews but in the deeper, more personal work of actually living this season differently.
The Midlife Circle is that space. Bi-weekly essays and The Midlife Edit, a private podcast, a Starter Library of tools, and a monthly personal video from me, from £19/month or £149/year.
And if you’re ready for the deepest layer, audio training, The Midlife Reset course, and four quarterly 1:1 calls with me, the Midlife Inner Circle is £297/year.
You don’t have to walk towards fifty alone. Come and do it properly.
